Semantic EnOcean: A Tool for Mapping Syntactic Device Descriptions onto an Ontology for the Internet of Things

摘要

This paper contributes to the semantification of the Internet of Things by outlining the efforts in including the Digital Concepts Smart EnOcean Gateway into the ISO/IEC 24752 Universal Remote Console framework (URC). Without our work, integrating the syntactic EnOcean device profiles into semantic environments is bound to an manual mapping of each profile to an appropriate ontology. In this paper, we describe a method and tooling for a semi-automated multistage process to map these profiles to an existing ontology. Strictly speaking, EnOcean device descriptions as given by a commercial EnOcean gateway, namely Digital Concepts Smart EnOcean Gateway, are mapped onto a smarthome ontology, namely DogOnt. As a side effect, the ontology is enhanced to fit the requirements of the device descriptions and extended by the actual devices. Finally, with the resulting ontology as a starting point, URC standard-conform, semantically enriched abstract user interface descriptions are generated. Through semantic enrichment of these User Interface Sockets, the functioning and purpose of the corresponding devices becomes machine-understandable and therefore can be easily used in semantic environments like Smart Homes. Without this additional semantic information, an automated generation of comprehensible user interfaces based on User Interface Sockets would not be feasible.
